김진수 교수의 연구실은 천연가스 및 석유 정제 공정에서 발생하는 산성가스(특히 황화수소 및 이산화탄소) 제거 기술에 중점을 두고 있습니다. 특히 흡착, 흡수, 막 반응기 기반의 탈황 기술과 함께 허브 펠로우 막 컨택터와 같은 최신 수소화 기술에 대한 연구를 진행하고 있습니다. 또한 도시 하수처리장에서의 암모니아 및 암모니움 이온 제거를 위한 생물학적 처리 기술, 예를 들어 Chiarella vulgaris를 활용한 질소 제거 기술에 대해서도 연구하고 있습니다.

Natural gas, refinery gas, and coal gas contain acid gases such as hydrogen sulfide (H2S) and carbon dioxide that must be removed from the gas stream due to the toxicity of H2S and to prevent corrosion to piping and production facility caused by the acid gases. In this article, current technologies for the acid gas removal are selected and reviewed. The review includes absorption, adsorption, conversion of H2S into elemental sulfur, and membrane reactor for H2S decomposition and desulfurization.
The capability of Chiarella vulgaristo remove nitrogen in the form of ammonia and/or ammonium ions from wastewater effluent in a local wastewater treatment plant (i.e., the Mill Creek Plant in Cincinnati, Ohio, U.S.A.) was studied. The wastewater effluent leaving the plant was found to include high concentrations of nitrogen (7.7±0.19 mg/L) (ammonia (NH <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> ) and/or ammonium ion (NH <inf xmlns:mml=
